Supplementary Figure 10: Projections on principal components for neurons with different selectivities in the LPFC.
From: Mixed selectivity morphs population codes in prefrontal cortex

We constructed a pseudo population of LPFC neurons consisting of equal numbers of neurons with CS, LMS, and NMS (27 neurons each, as in Fig. 6). (a) We performed PCA on the responses of the population without neurons with NMS, during Delay 1, and projected the responses of both Delay 1 (plotted in blue) and Delay 2 (plotted in red) onto the top two principal components. (b) Same as (a), but with responses projected onto the PCA space built with Delay 2 activity. (c – d) Same as (a – b), but with responses of the population comprised of only of neurons with NMS. (e – f) Same as (a – b), but with responses of the population without neurons with LMS. (g – h) Same as (a – b), but with responses of a pseudo population comprised only of neurons with LMS. (i – j) Same as (a – b), but with responses of a population without neurons with CS. (k – l) Same as (a – b), but with responses of a pseudo population comprised only of neurons with CS.
